I just built up a custom Ti bike and had this debate, so I'll share my perspective and suggest a 4th alternative for you. I went with Di2 internal routing and a Di2 groupset. The look is very clean and it works great.
The 4th option: Ask your shop about some cable guides that can bet attached to the frame via metal collars. I haven't seen them, but I hear that they can be found. Get your frame drilled for Di2 and have the holes plugged with grommets. It won't look really clean for the few first years but you can remove the metal collars when you upgrade to Di2 and you won't have brazed on cable guides for life.
Glad you're happy with your choice! Your 4th option is an idea! I remember those collars from way back. Thanks for the suggestion. Will look into this possibility.
Just go Di2 now- cable operated group sets are an anachronism, you're not planning on running 27&1/4" wheels I assume?
How could you tell?
I'll continue to run them wheels for as long as Sheldon
I also just had a custom ti frameset built.
I went external for mechanical group.
After riding internal cabled bikes for several years, I wanted something that shifted flawlessly and was easy
to work on- so external cables fit the bill.
I also wanted flawless bearing surfaces that are durable and noise free. So Chris King headset and threaded bb.
I did go for tapered steered fork so I have the King headset that looks integrated on top and has a big cup on the bottom- it is actually really cool.
I used a mechanical Dura-Ace 9000 group. It is flawless. The only thing I could possible gain from DI2 is the possibility of using the climbing shifter on the tops.
There you have it. My goal was to have a sweet but simple bike. Noise free and easy to work on. Mission accomplished.
It is 1 lb heavier than the carbon bike that it replaced. But it does not go slower anywhere that I can tell and it is way more comfortable.
Very well put and reasoned! You're making me take a second look at mechanical...arggh.
To be honest, my research did not go deep wrt tapered headset and bb. For the former, I'm a small/light person so don't think that I'll be pushing the boundaries of std 1.125" and for the latter external outboard bb is currently the most standard.
Mine will be internally cabled, for the clean look and the minute aero gains (???).
I'm crystal-balling perhaps wishful thinking that mecahnical will be around for a while yet. I'll be more concerned about disc brakes taking over; sorry if that is throwing you a wobbly as another thing worthwhile considering. It's actually not that easy buying/choosing a bespoke bike.
Your logic is appealing as well. I do think mechanical will be around for a while yet. The single most prohibitive factor for Di2 ownership is cost. Ui2 costs at much as mechanical Dura Ace. Your average cyclist (working bloke with a family and monthly payments to meet) can realistically justify mechanical Ultegra, not Dura Ace. I may well be wrong, but I don't see rim brakes going away anytime soon for road bikes. Cross bikes possibly will see a wider adoption but discs on road bikes are a solution looking for a problem.
I agree. It's not all that easy getting a custom frame if one puts some thought into the process.
This is the truth. There is always something "around the corner" but at present it is really hard to make up your mind about a bike you intend to ride for the long haul. My guess is that mechanical is going to be with us for a long while. There are just too many great frames out there that will need new groupsets, but once Shimano gets electronic down to the 105 level I think we'll see half of road bikes sold with it. I'm less certain about disc brakes because they involve such a change in frame size and wheel selection. All the justifications for it seem to pivot on some edge case where they are marginally better, but I don't see the breakthrough advantage relative to the hassles.
Well said. I think most of us just want to buy into the technology at the point where the "something around the corner" has just passed us by and not before. Nobody likes to pay full retail for something only to find out a month later that the new model is out. And we are still turning the corner right now.
I'd go internal drilled that will fit full housing if you go mechanical. Although it adds weight, the cable friction issues with full housing are really unfounded.
The main issue is to make sure that the hole at the head tube is large enough for two housing sections instead of just one wire.

I don't quite understand. Why the need to make the hole at the head tube large enough for two housing sections?
Ahhhh, just get mechanical now and build another frame with electronic. Didn't some mtb pioneer say that wealth should be measured by how many bikes one owns? Alas, I have to admit that I'm just a poor boy.
Alas, I'm not made of money myself.
